By downloading this file, you acknowledge that you agree to our Terms of Service

Detailed Description

This handler generates an expiring URL for S3. Expiring URLs take a bucket, a key (path + filename) and an expiration and build up a special URL that will give the user access to the file only for a certain time period.


This handler requires two info values for AWS authentication: Access Key ID and the Secret Access Key. These are analogous to username and password.

To find authentication values from the AWS account:

  1. Navigate to the following URL:

  2. Click the "Security Credentials" link (if you are not logged in, you will be prompted to do so).

  3. Click the "Access Credentials" link. Here you will find a list of your Access Keys.

  4. Use the Access Key ID to configure the accesskeyid info value of this handler.

  5. To retrieve the Secret Access Key, click the "Show" link next to the Access Key ID that will be used.

  6. Use the Secret Access Key to configure the secretaccesskey info value of this handler.
